220 BIUCHYPHYLLUM. 



the Perrno-Carboniferous beds of India by Feistmantel. The latter 

 specimens are, however, fragmentary, and while considerable doubt 

 must remain as to their true affinities, Feistinantel's generic deter- 

 mination may perhaps be retained for the present. The genus has 

 also been recorded from Argentina.

Type. Nos. 5511-12, 5518, Mus. Geol. Surv. India, Calcutta. 



Stem striated ; five or more leaves in a whorl. Leaves coriaceous, 

 forked two or three times. Median nerve strong, dividing dichoto- 

 mously twice or thrice to supply the segments of the leaf. 



Feistmantel described this species from the Barakar Group of 

 India. The leaves appear to be longer and stronger than in 

 Schmalhausen's plant. The Indian species has also been recorded 

 from Argentina. 



Not represented in the British Museum collection. 



Genus BRACHYPHYLLTJM, Brongniart, 1849. 

 [Tableau Veget. foss., p. 69.] 



" Branchlets generally thick, clothed with very short, spirally 

 arranged, scale-like leaves, apparently somewhat fleshy, with a 

 broad, rhomboidal base, usually furnished with a dorsal keel, 

 prolonged into a blunt or sharp point." 



As Mr. Seward : has remarked, this genus is very unsatisfactory 

 and difficult to define accurately. It is almost entirely a Mesozoic 

 type, occurring in the Rhaetic, Jurassic, and Wealden rocks. 

 Feistmantel has doubtfully compared some twigs of Coniferous 

 affinities belonging to the Glossopteris flora with the Mesozoic 

 members of this genus.
